PHPとMySQLを使用したログインと登録は、応答としてhtmlタグを表示します

Question

私はログインと登録活動を行っています。
ログインしてデータベースに登録することもできません。アクティビティのデータをそれぞれlogin.phpとRegistration.phpに送信します。私はWampサーバーを使用しています。

問題は、サーバーからの応答がHtmlタグとして返されるBackroundTask.javaにあります。私はHTMLでトーストメッセージが表示され、正しい値を使用してログインしようとしたとき、私はlogin.php & registration.phpのエコーメッセージログインアクティビティで

BackgroundTask.java

public class BackgroundTask extends AsyncTask<String, Void, String> { 

// AlertDialog alertDialog; 

Context ctx; 
BackgroundTask(Context ctx) 
{ 
    this.ctx=ctx; 

}

} 

} 

からそれらを排除するにはどうすればよいですこの

ログインページのようなタグは、上記のように表示されています。参考のため

以下のように

は、登録ページの値を充填した後、私は

<?php 
db_name="citizen"; 
$mysql_user="root"; 
$mysql_pass=""; 
$server_name="localhost"; 

$con=mysqli_connect($server_name,$mysql_user,$mysql_pass,$db_name); 

if(!$con) 
{ 
echo"Connection Error..."; 
} 
else 
{ 
echo"Database connection Success..."; 
} 

?> 

init.php自分のコードに取り付けられたトーストにのみ <br>タグを参照します

login.php

<?php 
require"init.php"; 

$user_name=$_POST["login_name"]; 
$user_pass=$_POST["login_pass"]; 

//$sql_query=mysqli_query($con,"SELECT * FROM reg WHERE 'Email' = '$user_name' AND 'Password'='$user_pass'"); 
$sql_query="SELECT Name FROM reg WHERE Email like '$user_name' AND Password like '$user_pass';"; 
$result=mysqli_query($con,$sql_query); 
//$row=mysqli_fetch_array($result); 
//$data=$row[0]; 
if(mysqli_num_rows($result)>0) 
//if($data) 
{ 
echo"Login Success..."; 
} 
else 
{ 
echo"Login Failed!Try again"; 
} 
//mysqli_close($con); 
?> 

Registration.php

<?php 
require 'init.php'; 
$name=$_POST["user"]; 
$address=$_POST["address"]; 
$user_pass=$_POST["user_pass"]; 
$emailid=$_POST["emailid"]; 
$zip=$_POST["zip"]; 
$mob=$_POST["mob"]; 
$sql_query="INSERT INTO reg VALUES('$name','$address','$user_pass','$emailid','$zip','$mob');"; 

if(mysqli_query($con,$sql_query)) 
{ 
echo"Registered Successfully"; 
} 
else 
{ 
echo"Registration Failed"; 
} 

?> 

Login.java

public class Login extends AppCompatActivity {

    Pattern pattern = Pattern.compile(EMAIL_PATTERN); 
    Matcher matcher = pattern.matcher(email); 
    return matcher.matches(); 
} 

// validating password with retype password

    } 
    return false; 
}

{ 
    startActivity(new Intent(this, Registration.class));

    Pattern pattern = Pattern.compile(EMAIL_PATTERN); 
    Matcher matcher = pattern.matcher(email); 
    return matcher.matches(); 
} 
} 

でも警告ボックスになるほど同じhtmlタグ。私はアンドロイドの初心者ですが、私はまだそれを学んでいます。この問題を解決するのを手伝ってください。どんな提案も大歓迎です。

私は修正されたコードが

<?php 
$db_name="citizen"; 
$mysql_user="root"; 
$mysql_pass=""; 
$server_name="localhost"; 

$con=mysqli_connect($server_name,$mysql_user,$mysql_pass,$db_name); 

if($con) 
{ 
echo"Connection success..."; 
} 
else 
{ 
echo"Connection failed..."; 
} 

?>
